I purchased them from Sweet Arrow Reptiles, but Don is a great guy and has been very supportive. He has offered to pay for any treatment if they are ill and has asked to be kept abreast of their progress. I have to emphasize I have not seen them yet. My neighbor has them and she is still relatively new to cresteds. I will be more comfortable once I have seen them myself but their have been no new spots as of now. I am on vacation but will return home tomorrow. Hopefully, all will be well!
